To all whom it may concern:

Be it known that we, HENRY G. VoIeHT and CHARLES J. CALEY, citizens ofthe United States, residing at New Britain, county of Hartford, State ofConnecticut, have invented certain new and useful Improvements in LockConstruction, of which the following is a full, clear, and exactdescription.

Our invention relates to improvements in looks, and has for its objectmeans for connecting a lock to a door in a simple and eflicient manner.

In the drawings, Figure 1 is a front elevation of an escutcheon platemember of the lock, certain parts being removed. Fig. 2 is a verticalsection, a certain part being shown in elevation. Figs. 3 and 4 areviews corresponding respectively to Figs. 1 and 2, but showing amodification.

1 represents the stile of a door to which the lock is to be applied.

2 is the case of a lock of the well-known rim lock type.

2 is the rear cover or cap-plate which is secured to the case 2 afterthe lock mechanism (not shown) is placed therein, the said plate beingsecured in any well-known manner, as by ordinary machine screws (notshown). Projecting rearwardly from the cap-plate 2 is a hollow tubularboss 2 In the drawings two of these tubular bosses 2 are shown. Wherethese bosses 2 meet the cap-plate 2 there is a somewhat reduced threadedportion 2 arranged to receive the threaded end of a cylinder lock 3, sothat the roll-back 3 thereof will stand within the case 2 to properlyengage the lock mechanism, in the well-known manner.

4 is an escutcheon plate adapted to the opposite side of the door fromthe case 2. The tubular extension 2 is adapted to extend through apassage in the door stile near and through a passage in the escutcheonplate 4, the outer end of said tubular extension being threaded toreceive a clamping nut 5.

6 is a rose plate or finishing plate adapted to'bear against theescutcheon plate 4 and overstand the nut 5, hiding the latter from viewwhen the parts are assembled. The cylinder lock 8 serves to hold thefinishing plate 6 against its seat, the flanged outer end of said lock 3holding said finishing plate 6 in place, as shown in Fig. 2.

The usual set-screw (not shown) carried by the case 2 and arranged toengage in a side groove of the cylinder-lock, in the usual man ner,retains it in place after proper adjustment has been efiected.

As will be seen, by this arrangement an absolutely accurate alinement ofthe parts may be effected, and at the same time the case 2, plate 4 andfinishing plate 6 may be properly positioned and firmly clampedtogether, the only manner of separating said parts being possible whilethe door stands open and access may be had to the means for holding thecylinder lock against removal.

It should be understood that the escutcheon plate may be of any desiredshape or design, in this instance its most important function being tofurnish a proper bearing for the locking device 5. The tubular bossaffords not only a broad bearing support and connection, but alsoprovides a passage whereby access may be had to the interior of the lookfrom the outside through the medium of a proper instrumentality, forexample, such as a key adapted to the cylinder lock 3. NVhere a cylinderlock is employed, it, in turn, serves to reinforce the strength .of thetubular boss 2 for, as will be apparent, it would not only be necessaryto tear away the locking device 5 before the escutcheon could be removedand the lock released, but it would also be necessary to break theconnection of the cylinder lock 3 with the cap-plate 2 which would bepractically impossible and an act that would not be resorted to in viewof the many easier methods of obtaining an unlawful entry.

In Figs. 3 and 4, we have shown a modification in which, instead ofextending the tubular boss entirely through the door, it is extendedpartially through the same, in this instance a companion tubular bossbeing formed on the rear of the escutcheon plate. The bosses in thiscase are flanged inwardly to provide a bearing for clamping devices inthe form of screws to take the place of the clamping nut 5. In thisinstance, as before, the protecting rose may be employed but, as shown,may be of a different form. In Figs. 3 and 4, 1 represents the doorstile, 2 the lock case and 3 the cylinder lock, as before. member, and aclamping device carried by is the capplate, 2 is the inwardly extendingtubular boss from the cap-plate 2 said boss being provided with aninwardly directed flange 2 4 is the escutcheon plate, 4* is a tubularboss projecting rearwardly therefrom and corresponding to the boss 2. 4is a flange on the boss 4" corresponding to the flange 2 These. flangesaflord clearance room for the securing screws 5 to draw said bossestoward. each other to clamp the lock case 2 and escutcheon 4 tightlyagainst op posite sides of the door. In this instance the screw-threadto receive the threaded end of the cylinder lock 3 may be formed at theinner edge of the flange 2 6" is the roseplate overstanding the -cavitywithin the boss 4?, as best seen in Fig. 4. In this instance, as before,the protecting rose 6 is held in proper position by the flange at theouter end of the cylinder lock 3.

The lock case on one side constitutes one member and the escutcheonanother member to be clamped to the door, and in the claims we will usethese terms in order to give the proper scope thereto.

What we claim is:

1. In a device of the character described, an outside member, an insidemember, a threaded annular boss carried by and projecting to the rear ofone of said members, a coupling device carried by the other memberarranged to operatively engage the end of said boss, said boss having apassage, and a lock mechanism detachably mounted therein.

2. In a device of the character described, an inside member, a separateoutside member, a tubular boss projecting from one of said membersthrough the other member, and a separate clamping means arrangedexternally of the last mentioned member cooperating with said boss.

3. In a device of the character described, an inside member, an outsidemember, a tubular boss projecting from one of said members through theother member, a clamping means arranged externally of the other membercooperating with said boss, a guard for said clamping means, and meansto hold said guard in place.

4. In a device of the character described, an inside member, an outsidemember, a tubular boss projecting from one of said members through theother member, a clamping means arranged externally of the other membercooperating with said boss, a guard for said clamping means, means tohold said guard in place, and a device carried by the first mentionedmember to lock the last mentioned means against disengagement.

5. In a device of the character described, two members to be connected,a threaded tubular boss being carried by one of said members andprojecting toward the other the latter and arranged to engage saidtubular boss to clamp said members on opposite sides of the door, andmeans carried by the last mentioned member to cover and protect saidclamping device.

6. In a device of the character described, two members to be connected,a tubular boss carried by one of said members and projecting toward andthrough the other member, the extremity of said tubular boss beingexternally threaded, a correspondingly threaded clamping member arrangedto co- .act with said tubular boss to draw said members toward eachother, and a protecting device arranged to cover and hide said clampingdevice.

7. In a device of the character described, two members to be connected,a threaded tubular boss carried by one of said members and projectingtoward and through the other member, the extremity of said tubular bossbeing threaded, a correspondingly threaded clamping member arranged tocoact with said. tubular boss to draw said members toward each other, aprotecting device arranged to cover and hide said clamping device, and alock actuating mechanism passing through said tubular boss andaccessible at one side of the door.

8. In a lock mechanism, a lock case, an integral tubular boss extendingto the rear thereof, an escutcheon plate arranged to bear against theopposite side of the door from the lock case, said tubular boss passingtherethrough, a securing device cooperating with the free extremity ofsaid tubular boss and the escutcheon plate, and a detachable protectingdevice for said locking device.

9.
